Dysfunctional Rules IX: 1d3 Dysfunctions from the 8th Level List

[Kaleph]

The sha'ir gets craft wondrous item at Level 13 as a sort of bonus feat, but can only use it to create an iron flask that can be used to trap a genie.
The prerequisite spell to create an iron flask is trap the soul, an 8th level spell.

Now according to the DMG, "if spells are involved in the prerequisites for making the item, the creator must have prepared the spells to be cast (or must know the spells, in the case of a sorcerer or bard)"; depending on how you read the retrieval rules, a sha'ir needs to be at least level 15 or 16 in order to fulfil the prerequisite, so the class gives you an ability that you have to wait sorta 3 levels until you may use it.
